This Costco-exclusive 2-pack bundles two Learn by Sticker activity workbooks from Workman Publishing, the popular educational publisher behind the series. Learn by Sticker books combine curriculum-based practice with a rewarding sticker reveal mechanic: children solve problems — math, phonics, or word study — and use numbered stickers to uncover a hidden image one piece at a time.

Each book is designed for children ages 5 and up, depending on the specific titles included. The format reinforces foundational skills such as addition, subtraction, phonics recognition, and vocabulary while keeping kids engaged through a hands-on, creative activity. Completing each spread rewards children with a finished illustrated scene built entirely from their correctly answered stickers.

Workman Publishing's Learn by Sticker series is widely used as a supplemental learning tool at home and in classrooms. The 2-pack format offers additional practice across two different skill areas or difficulty levels, making it a strong value for parents looking to support early learning.
